International Business in Law or International Taxation?

I'm a foreign student seeking for a LLM.I read a lot of things here and even though that was quite helpfull I still have some doubts.I've already got specialization in International Law (which includes subjects as International Tax, Arbitration, International Contracts, ...)

First I was trying to find a LLM focused on International Business in Law, but now I'm quite confused. I've read a lot here about Taxation. Should I make up my mind on Taxation instead of Business? How are opportunities in the US for lawyers who do LLM in International Business? (as some have said here in others topics I also find very important the practise)

My other question is about the top universities. I also read about that here. Is this really important or it is only for good impression? e.g. if I'm going to Boston University to do Taxation am I going to miss something really special in NYU?

I am not extremely versed in LLM programs, but re choice of university, it does make a huge difference which you chose in terms of your subsequent career prospects. NYU's tax LLM is very highly regarded. Harvard also has a very strong general LLM program that may be worth considering. I don't know what the job market in the US is like generally for Intl Business LLMs, but as a very general matter the legal job market in the US is quite poor at the moment.
